The page contains links to articles and coding samples used predominantly, but not exclusively between 2003 and the present time. The predominant operating systems were z/OS 1.3. through to z/OS 2.5.

Where CICS/TS has been part of the equation it was typically CICS/TS 3.1 up to the current version in use which is CICS 6.1.

Programming in IBM Assembler started in 1972 after buying a copy of "Assembler Language Programming the IBM System/360" by George Struble.
